Ok so, impress-2020 guesses the manifest URL every time based on common
URL patterns. But the right way to do this is to read it from the
modeling data! But also, we don't have a great way to get the modeling
data directly. (Though as I write this, I guess we do have that
auto-modeling trick we use in the DTI 2020 codebase, I wonder if that
could work for this too?)
So anyway, in this change, we update the modeling code to save the
manifest URL, and also the migration includes a big block that attempts
to run impress-2020's manifest-guessing logic for every asset and save
the result!
It's uhh. Not fast. It runs at about 1 asset per second (a lot of these
aren't cache hits), and sometimes stalls out. And we have >600k assets,
so the estimated wall time is uhh. Seven days?
I think there's something we could do here around like, concurrent
execution? Though tbqh with the nature of the slowness being seemingly
about hitting the slow underlying images.neopets.com server, I don't
actually have a lot of faith that concurrency would actually be faster?
I also think it could be sensible to like… extract this from the
migration, and run it as a script to infer missing manifest URLs. That
would be easier to run in chunks and resume if something goes wrong.
Cuz like, I think my reasoning here was that backfilling this data was
part of the migration process… but the thing is, this migration can't
reliably get a manifest for everything (both cuz it depends on an
external service and cuz not everything has one), so it's a perfectly
valid migration to just leave the column as null for all the rows to
start, and fill this in later. I wish I'd written it like that!
But anyway, I'm just running this for now, and taking a break for the
night. Maybe later I'll come around and extract this into a separate
task to just try this on all assets missing manifests instead!
Ahh, I guess I missed these, I think they're maybe not actually used in
the app is why? cuz they're all default values that are overridden at
the actual call sites. But I ran into it when running `Pet.load` in the
console, and yeah let's just fix 'em up!
This hasn't worked for a while, and I don't know an API off the top of
my head to drop in for it. Let's just delete it for now, and revisit it
later if we want to!
Dang, I'm really wishing I'd opened this sooner cuz I didn't realize it
would be THIS easy!!
The bug was that the `t` method started taking Ruby keyword params
instead of a hash object for `options`, so the syntax changed.
Womp womp!
Really don't know why this wasn't a problem with Apollo (or was it??),
but yeah, don't save when there's a save error!! Then we reset the
mutation state when the outfit state changes.
It's weird to be reading this code and be like. was this not always an
issue? Maybe something in Apollo prevented this? Did we use optimistic
UI or something? Idk?
There's still an issue with it infinitely retrying in an error state
though.
Just sharing this out to gather info, since this might be coming kinda
soon!
I also moved the announcement higher up in the template, because it
gets broken on the user lists page which uses floats quite a bit for
the site header—and tbh I feel like this is better anyway lol.
In the impress-2020 app, we use this to prepopulate certain GraphQL
data into the Apollo cache when SSR'ing a page. We don't do that here,
so, goodbye!
The wardrobe-2020 app had a cute drawer that embeds the item page, but
honestly I don't think it was that valuable, and especially not when it
means we have to basically maintain two item pages lol. Let's decrease
the surface area!
A really really simple change! It works on the item page, the item
index page, item search, the homepage, and the item lists page.
The main reason I avoided this for so long (even before modernizing the
Rails app) was that the ElasticSearch stuff felt like it made it messy?
But now it's pretty simple, and it works in search already cuz I did
that when I implemented item search, so, nice!
Ok cool, I have just not been running any of this since moving out of
impress-2020, but now that we're doing serious JS work in here it's time
to turn it back on!!
1. Install eslint and the plugins we use
2. Set up a `yarn lint` command
3. Set up a git hook via husky to lint on pre-commit
4. Fix/disable all the lint errors!
Rather than letting the fact that the server API models outfits a bit
differently (underscore keys, integer IDs for things), I'd rather
convert it to the familiar field names and expected types!
This came in a few parts!
1. Add meta tags to let us know we're logged in.
2. Install React Query, which has the data-loading sensibilities I like
about Apollo without the GraphQL that has honestly been a drag.
3. Replace the outfit-loading and outfit-saving calls with API calls to
the main app.
4. Update the main app's API calls to use our more flexible data
constructs like "pose".
Would've loved to do this more incrementally, but it's hard to! You
can't split out outfit-loading and outfit-saving, or auth from any of
that, or the state gets all out-of-sorts.
Still, this is a good nugget we've pulled out all-in-all, and one that
people have been asking for! Can maybe look to logged-in item search
soon too, for own/want data?
Moreover, this code is in a bit of a flimsy state anyway: it'll kinda
work if you're logged in at impress-2020.openneo.net, but that wasn't
intentionally engineered, and I'm not sure exactly what circumstances
cause those cookies to send vs not send?
My intent is to clean up to replace all this with login code that
references the main app instead… this'll require swapping out some
endpoints to refer to what the main app has, but I'm hoping that's not
so tricky to do, since the main app does offer basically all of this
functionality already anyway. (That's not to say it's simple, but I
think it's a migration in the right direction!)
I used the new profiler tools on this page, and noticed a lot of
allocations in the Globalize library, which we use for translating
database records. I realized that we were loading all of the fields of
not just all of the items on the page, but all of their translation
records in all locales! We used to scrape data for lots of languages, so
that can be quite a lot!
Unfortunately, Rails's `includes` method to efficiently preload related
records always loads all fields, and simply can't be overridden.
So, in this change we write manual preloading code, to identify the
records we need, load them in big bulk queries, and assign them back to
the appropriate associations. Basically just what `includes` does, but
written out a bit more, to give us the chance to specify SELECT and
WHERE clauses!
It shows up in development always, and if you're logged in as Me
Specifically in production!
I'm using this to poke at memory usage for pages that seem suspicious.
I don't know why our app reliably grows so large in RAM, but my hunch is
that maybe there are some pages that just use a truly large amount to
begin with - and I've learned Ruby doesn't release memory back after
it's GC'd, it just grows the process and keeps the free space to itself
in its own heap!
So I'm just eyeing pages that I know *can* have a lot going on, and
seeing what I find!
We used to do this for weird clever caching tricks that I don't think
were actually very effective. We stopped using this a few months ago,
and now I'm finally cleaning up this supporting code!
Huh, Arel can *sometimes* handle just having an attribute stand in as
"X is true" in a condition, but sometimes gets upset about it. I guess
this changed in Rails since we recently wrote this?
Specifically, item search would crash on "is:nc" (but *not* "is:np"),
saying:
```
undefined method `fetch_attribute' for #<struct Arel::Attributes::Attribute relation=#<Arel::Table:0x0000000109a67110 @name="items", @klass=Item(…), @type_caster=#<ActiveRecord::TypeCaster::Map:0x0000000109a66e90 @klass=Item(…)>, @table_alias=nil>, name="is_manually_nc">
```
The traceback was a bit misleading (it happened at the part where we
merge all the scopes together), but that hinted to me that it working
with an attribute in a place where it expected a conditional. So I
converted the attribute in the `is_nc` scope to a conditional, and made
the matching change in `is_np`, and that fixed it! Ok phew!
The URL anchors were getting like. double-encoded? The `closet[]` part
was encoding as `closet%255B%255D`. Maybe a thing in Rails, where you
need to mark them `html_safe` to insert them in a URL like that?
Well anyway, those URLs are redundant now, I just have it link straight
to the same outfit page as the big link!
Now, like in DTI 2020, opening an outfit will go straight to the editor.
I'm not 100% on whether this is actually like. the superior behavior?
But I think it's good enough, and it's what the wardrobe-2020 code
expects, so let's just roll with it for now!
Ohh I see, I made a mistake converting this from Next.js routing. It's
not that we had a URL search parameter named `outfitId`; it's that if
you were coming from the `/outfits/:outfitId` route, it would use that!
I still haven't gotten the rest of the site to point that route to this
page, but I'll do that in a later change.
Notable things:
- We used to have the parameters in the hash (`#`) part of the URL.
- We used to use the key `outfit=123` instead of `outfitId=123`.
In this change, we add backwards-compatibility for these things, while
still keeping the latest behavior too, with no change to the URLs we
generate!
Looks like the version of Prettier I just installed is v3, whereas our
last run in the impress-2020 repo was with v2. I don't think we had any
special config in that project, I think these are just changes to
Prettier's defaults, and I'm comfortable accepting them! (Mostly seems
like a lot of trailing commas.)
Idk if this used to be different or what, but it looks like the current
behavior is: if you delete a closet list, it'll leave the hangers
present, but Classic DTI would not show them anywhere; but Impress 2020
(until recently) would crash about it.
Now, we use `dependent: :destroy` to delete the hangers when you delete
the list (which I think makes sense, and is different than what I
decided in the past but that's ok, and is what the current behavior
*looks* like to people!), and we add a migration that deletes orphaned
hangers.
The migration also outputs the deleted hangers as JSON, for us to hold
onto in case we made a mistake! I'm also backing up the database in
advance of running this migration, just in case we gotta roll back HARD!
This is an important workflow for people doing art stuff, I'm told! They used to use the Classic DTI broken image UI for this, but now that that's uhh Fully Gone, let's add this more explicitly!
Ah right, the CSS reset only applies in the ScopedCSSReset container, which doesn't work for elements portaled out with the <Portal> component (which a LOT of Chakra components use for things like tooltips etc).
Here, we take advantage of <Portal> having a hardcoded classname .chakra-portal, and applying it to them too!
This was used by the Neopia server to send us the modeling data it requested out-of-band. But now we do all our modeling requests back in-app again, so we don't need this!
Okay, this is a process that idk if it's even been working for a while anyway, I don't think Neopets translates item names anymore?
And it's crashing when I try to model stuff now, so like. yeah ok I'm fine with just skipping this, it's a shame to lose out on potential data going forward but *I think there just isn't data to get anyway*
I think we used this for both conversion to image, and also for CORS stuff when rendering Flash-based previews… let's trash it, I don't want to be growing our hard drive with files I don't think we use anymore!
If I'm wrong and it turns out we do use them for something, then like. hey I'm sure we'll find out soon enough, and it's very recoverable operation.
I hope this doesn't cause problems! But yeah, with Puma doing threading, and maybe switching to Falcon someday to get even better concurrency properties, I feel like this will probably be fine?
And it makes the UX a loootttt better, to be back in the world where all these forms just work, whew.
Oh okay, I was misinterpreting the error: it was that our NEOPETS_URL_ORIGIN secret value isn't the real Neopets.com IP address anymore, so amfphp requests were just plain *always* failing in production. Oops!
I've remove that environment variable from our production config, and now modeling is working in the bulk thing!
Also I'm noticing that we're using puma these days, which does good threading stuff. I think there might be merit to switching over to Falcon because of just how async-y our stuff is, but having 5 threads going is honestly probably good enough that I don't need to worry too much about mutual blocking, and could probably just write stuff to get Neopia out of the picture like *right now*. Neat!
Okay so… I'm worried about this because of Rails whole single-threaded situation, which doesn't really let it handle blocking on external network requests very well.
Ultimately I think we're gonna have to do a clever thing but idk quite what?
I should look into whether like, puma + the new async stuff can enable Rails to be more tolerable about this, and handle a few requests at once, instead of having to have the Neopia server doing it. (Right now, the Neopia server isn't really doing its job quite right, because it depends on the Rails app being *local* to send stuff to it.)
But for now, let's just extend the timeout, cuz it's basically always getting hit in production—because there's currently no other way to do modeling, oops lol
Just find_all_by's that I never cleaned up
Oddly enough, I still got a "neopets seems down" message out of this, idk if that's an actual bug or just sluggishness rn
